his `.Seat on l the tractor.

i 1,29 supporting asetof binder control #levers- 6o binderfframeare shaftsfl adapted `ltojbe As the binder is pulled by a tractor, of course, no operator sits on the binder where he can watch the binding mechanism and the twine can source of supply of twine for the binder. Tt is accordingly desirable that the twine can be located where the operator may watch it from his seat on the tractor. Accordingly, it proposed to place this twine can on the binder hitch frame where it may be watched bythe operator, This improved mounting will now be described.` Transversely arranged on the members 17 and 28 is a transverse crank rod 31, which pivotally carries a vertically disposed twine can 3,2, the crank being hinged to the bottom of the can, as shown in Figure 8. Th-e rear top side of the can has a pivotal link connection 33 with the post 12 on the binder main frame.

Another feature of this invention contemplates the use of a counterbalance means between the binder main frame and the hitch draw frame. This means comprises a spring 3ft connected between the post 12 on the binder main frame and the cross piece 22 of the hitch draw frame, as shown. Thus, the spring exerts a force constantly to pull up on the draw frame.

The operation and use of the improved structure of this invention will now be described. The b-inder hitch draw frame being pivotally connected by the pivots 18 and 20 to the binder main frame, can be manually pushed up to fold the same alongside the binder, upon removal of the vertical pivot pin Q1 from the tractor drawbar and disconnection of the telescopic shaft section 2G, the hitch then being adapted for movement to thevdotted line position shown in Figure 1. A hook 35 always carried by a suitable part of the binder frame is then in position to hook onto any part of the hitch structure, such for example as the control levers 30, to retain the hitch structure in its upwardly folded position. Thus, the binder is materially narrowed for purposes of convenient transport.

The counterbalancing spring 34, of course, exerts a force which materially assists in the raising of the hitch structure and, incidentally, when it is desired to connect the hitch to the tractor drawbar 16 by means of the pin 21, it will be found that the spring resiliently floats the hitch draw frame and makes an easy job of connection of the binder to the tractor, as the operator does not have tolift the whole weight of the binder hitch.

As the hitch is folded upwardly, the twine can 32 maintains its vertical position because of its pivotal mounting on the crank 81 and the rod 33 connecting its top with the post 1Q,

as will be understood.

It is to be understood that in this disclosure there has been shown an illustrative embodiment of one form of this invention which it may assume in practice, and that obviously it 'l may be altered to assume other forms and embody changes in its structure which will not depart from the spirit and scope of this invention. Tt is the intention to cover all such changes as do not materially depart from the present invention, as indicated in the appended claims.

That we claim is:

1. The combination with a binder having a main frame, of a hitch therefor, said hitch comprising a draw frame pivotally connected to the binder main frame on horizontal pivots and adapted for detachable connection on a vertical pivot to the drawbar of a tractor, and a twine can pivotally connected to and carried by the draw frame.

2. The combination with a binder having a main frame, of a hitch therefor, said hitch comprising a draw frame pivotally connected to the binder main frame on horizontal pivots, a rod on the draw frame, and a twine can pivotally connected to and carried by said rod.

3. The combination with a binder having a main frame, of a hitch therefor, said hitch comprising a draw frame pivotally connected to the binder main frame on horizontal pivots, a rod on the draw frame, a vertically arranged twine can pivotally connected at its bottom to said rod, and a pivotal lilik connection from the `top of the can to the binder main frame.

1. The combination with a binder having a main frame, of a hitch therefor, said hitch comprising a dra-w frame pivotally connected to the binder main frame whereby said draw frame may be folded upwardly, a vertically disposed twine can mounted on the draw frame, and means connected to the can for maintaining said can in its vertical position when the draw frame is folded.

5V. The combination with a binder having a main frame, of a h itch therefor, said hitch comprising a draw frame embodying a pair of forwardly converging members pivotally connected at their rear ends to the binder main frame, whereby said hitch frame may be folded upwardly, a twine can vertically carried on said frame, and means for maintaining said twine can in its vertical position when the hitch frame is folded.

6. The combination with a binder having a main frame, of a hitch therefor, said hitch comprising a draw frame embodying a pair of forwardly converging members pivotally connected at their rear ends to the binder main frame, whereby said hitch frame may be folded upwardly, a transverse rod on the hitch frame members, a vertical twine can pivotally mounted on the rod, a pivoted link connection from the can to the binder main frame, and a counterbalancing connection from the binder main frame to the hitch frame.

7 The combination with a binder having a frame, of a hitch therefor, said hitch being mais@ pivotally connected to the frame forupward folding, a twine can mounted on the hitch,

and means connected between thecan and frame for maintaining the can upright when the hitch is folded.

1 8. The combination with a binder havinga frameof a -hitch therefor, said hitch? being pivotally connected to the frame for `upward folding, a twine can and binder control levers V mounted on the hitch, and means for maintaining the can upright when the hitch is t folded. Y

9; The combination with a .binder having a frame including an upright at its frontend,

a hitch foldably connected to theframe, an upright twine can pivotally mounted on the hitch, and a pivot link connected beween the upright and can to maintain said canv in pari allelism with the upright when the hitch is folded. i l In testimony whereof we aiiix our signa- A tures. l
